Can I change way functions

int, str, float, list...
(basicaly every type-changing function)

are working?

P.S. magic-methods related question, as sad in tag

Answer 1

Answer 2

How do I change it

Answer 3

yes, you can. But it is not recommended to do that at work.
Also int, str, float... are classes and when you call them, you basically use their constructor
